Cluster Multicast: Socket is closed error

[Jesse Felter]

I am recieving this error in my logging, I am trying to track down why the apps we run are running very slowly. After a server reboot they run fine but a day later they are hanging and are slow. Perhaps there is a leak somewhere, this is the only environment I see this on and the only error that is put to logging is this one. I am running a one machine vertical cluster with two managed servers. Any ideas on what could be causing this would be greatly appreciated
